Top 500 Logo - Small

Solar Power World, the industry’s leading business-to-business publication, announces the release of the 2015 Top 500 Solar Contractors listThis is the most recognized annual listing of North America’s top solar contractors working in the utility, commercial, residential and off-grid markets.

Companies on the list are grouped by specific service (construction firms, developers, electrical subcontractors, EPCs, rooftop contractors, solar hot water installers), markets (commercial, off-grid, residential, utility) and states by 2014 installed capacity.

This year, a 24-contractor advisory board was established to assist us in verifying installation claims. The 2015 advisory board was essential to ensuring the Top Contractors list is as accurate as possible. A list of our advisory board is at the bottom of this release.

solarreviewsSolar Power World also received assistance and feedback from SolarReviews. The SolarReviews ‘Pre-Screened Solar Pro’ program is a performance-based quality accreditation for solar installers. Consumers and business owners looking to install solar can trust an installer with this badge, which appears in the print and digital editions of the Top 500 Solar Contractors list.

When it comes to solar hot water installers, this year’s list is determined by the number of residential and commercial projects installed in 2014. Contractors received one point per residential hot water installation and two points per commercial installation.

    Sun Edison delivered 640 MW globally in Q3 2015, with about a 1/3 of that in the US, and it’s nowhere on any of these lists?? Is this meant to be an objective ranking or a pay-in marketing tool?

    • Hi there,

      Those companies on our Top Contractors list must fill out an application each year, providing their installation numbers. We hope to have a more comprehensive list in the coming year.
